Antique furniture adds a vintage element to your home decor, but it can appear unsightly if crackle is chipping or peeling. Make crackle on antique furniture look more like decorative, faux-crackle paint by applying sealants, which will adhere the crackle while maintaining the original, vintage look of the furniture. Purchase all of the materials needed to make antique crackle look like paint from any home improvement or hardware store.
Sand the surface of the antique furniture very lightly using fine-grain sandpaper to remove any sharp or jagged edges of crackle. Do not press down as you sand, but gently glide the fine-grain sandpaper in circular motions over the crackle.
Brush off any dust or debris using a 2-inch filbert paintbrush.
Fill a paint tray with clear latex varnish, then coat the end of the paintbrush in the varnish.
Paint the clear varnish in an even layer over the entire piece of antique furniture. Allow the varnish to air-dry for 12 to 18 hours.
Apply a second coat of varnish, as before, and allow the varnish to air-dry for another 12 to 18 hours before using the piece of antique furniture.
